To all whomt may concern.'

Be it known that I, MARTIN .Ill/VALsrr, a citizen of the United States,and a resident ofthe borough of Manhattan, city, county and State of NewYork, have invented certain new and useful Improvements inFire-Extinguishing Apparatus, of which the following is a specification.i

My invention relates to fire extinguishing apparatus and is an.improvement upon the apparatus disclosed inmy pending applicationSerial No. 825,513 filed March 18,

Mv present invention consists offa simple and ueflicient extinguishermechanism, wherein a nely divided non-combustible substance, such as,for instance, sand, is maintained upon oscillating supports locatedadjacent the ceiling, and suchsubstance is released through the fusingfrom excessive heatof a fusible connection suoli as a-wire or link, saidfusing permitting the supports containing the non-combustible substanceto swing or oscillate and thus to empty their contents to Vquell thefire.

Figure 1 is a top plan view of my apparatus. u

Fig. 2 is a sectional elevation taken on line 24-2 of Iiig.` 1.

Fig; 3 is an enlarged detail of the ends of the supporting rods andtheir cooperating li as.

1F ig. 4 isa detail in perspectiveshowing the bearing of one of thesupporting rods.

Fig. 5 is an enlarged detail ofthe releasing mechanism and its relatedparts.

Fig. G is a .detail taken approximately on line 6 6 of Fig. l showingthe releasing lever. y

Fig. 7 is a section of the bracket and rock shaft taken on line 7-7 ofFig. 5.

Fig. 8 is a detail of the supporting bracket of the releasing lever andits hook taken on line 8-8 of Fig. 5.

Fig. 9 is a detail of the fusible link of my apparatus.

In the form of construction shown in the foregoing drawings, I employ aseries 0f in tei'dependent receptacles o r supports 1, liori# zontallysupported at a slight distance from the ceiling. These supports may beformed of metal and as herein shown by way of example are secured upon aseries of metal rods 2, which sustain them horizontally as hereinafterdescribed. In the accompanying Specification of Letters Patent.

Batented Sept. 9, 1919.

Application led July 29, 1914. Serial No. 853,786.

drawings two such rods are shown by way ofexample for each support.

Each of the supporting rods 2 is bent upwardly, as shown at 2t,` theupward bend terminating in a lip 2b which, `in the case of the firstseries of supports 1 engages the lugBupon a collar 3U: secured upon arock shaft-l by set screws 3b, the rock shaft 11 being rotatablysupported in wall brackets 8--8 near its respective ends. It will beunderstood, without further :reference thereto, that along the length ofthe rock shaft 11 additional `fixed collars and lugs 8 are provided tosustain as many supporting rods and supports 1 as may be provided forthe series of trays. The opposite ends of each of these rods 2 islikewise turned upwardly, as shown at 5, and terminates in a lip 5 whichlip serves as a support for the next succeeding support 1 as will behereinafter described. This `latter end of the supporting rod 2 isformed with a bearing 6 which pivotally engages a shaft carried bybracket arms 8a, securedto the wall of the room or loft. The nextsucceeding support land supporting rod 2 are similarly formed but thelip 2l thereof is arranged normally to rest upon the lip 5a ofthepreceding supporting rod and soon, until the last tray of the series isreached. l

From the foregoing description, it will be apparent, that when the lip2b of the first support "l of `the series is disengaged from the lugSupon the rock shaft 4,it will swing `from horizontal to verticalposition, thereby supports 1 to swing from horizontal to verticalposition.

I shall now describe the mechanism for causing the release of the firstsupport 1 of the 4series from its engagement with the lug 3 upon therock shaft 4. Upon the collar 3a of the rock shaft 4 another lug 9 ispro* vided, which in the normal position of the shaft is engaged 'by thehook 10 formed upon the upwardly extending arm 11a of a hell crank lever11, the horizontal arm 11b of whichcarries a weight 12 to accelerate theoscillation of said bell crank lever. vThis bell crank lever ismaintained in its normal position (whereby its hook 10 is in holdingengagement with the lug 9), by a hook nection such .as la fusible Wire1G is secured,

the otherend offs'aid Wire being tautly secured in any4 suitable mannerat the'other end of the room as'show'n at 16h.

' This Wire 16 mayconsist of one continuous strand of fusible metal orofone or more Vfusilble links 1Gd Which may be interposed betweenstrands ofordinary Wire or rope, a sample vof such links being shown inFig.

' 9 of my drawings.

I shall new` describe the mode of operation of my apparatus.

Ally the supports are inthe position shown in `Figs. 1 and 2. A firestarts beneath them, producing in its early stages a rise in temperaturesufficient to resul-t in fusing the fusible connection 16 or of theintei` posed link or links 16a whereby the release lever 15 and its hook13 are rendered free Yto oscillate, the'hook 13 thussivinging out ofholdingv contact with the arm l'lbof the bell cranklever 11 causing thehook 10 to vibrate out of yholding contact with the lug 9 on the collar- 3a of the rockjshaft 4. The

shaft ebeingl thus released will rotate under tl'ieweight ofthesupportsl, thereby releasing the lips Qbfrom holding engagement.v withVthe lugs 3 and Sconrthe''xed collars of the rock shaft l, Whereuponthetray Will ksiving from its normal horizontal position Vtoauapproxima'tely vertical position and empty its contents ofnon-'combustible material. As heretofore explained, the oscillation ofthis first tray'of the series vvill lresult in a similar oscillation ofthe second and the successive 'traysfof the series so that Ycombustiblematerial and their relation to one another may be made in any desiredform or dimension, the essence of my invention being that these supportsshall be capable of movement to Vempty their contents of finely dividednon-combustible maferial by reason of the fusing of a fusible supporttherefor.` It will also be understood that another form of releasingor'trigger mechanism may 'be substituted for the form shown and thatvarious modifications in detail may be made With-out departingi from thespirit of my invention.

Having descrilbed my invention, what I claim and desire' to secure -byLetters Patent is:

1. In -a fire extinguishing apparatus, the combinationof a. plurality ofoscillatingY sup` ports arranged in. series, an oscillating mem` bercarried by each of said supports except the last -to engage thesucceeding support; finely divided -non-combustible n'iaterial earrie'dby said sup-ports, and a fusible connection for holding and releasingthefirst of said supports.

2. In aY fire extinguishine` apparatus, the combination of a vpluralityvof oscillating' supports arranged in series, an oscillating` memlbercarriedby each of said supports except the last establishing connectionwith the succeeding support; finely divided nonconrbustilble materialcarried by said supports and a fusible connection for holding andreleasing the first of said supports.

In testimony whereof, I have hereunto set my hand in the .presence oftwo subscribing Witnesses.. K n
